I always check my EDCs to make sure they are not gravity knives, and that they can not be flicked open in any way, even if the blade is tight when opened.
What is the best method to tighten a pinned blade ? I have used a hammer against steel, but have found this can cause marks.
Is this the only way?
Thanks !!
